How to determine which path is being used?
Is it possible to determine which path is being used between two nodes?
Does the OLSR information tell that?   If so how do I read it?  
Of course it world be VERY useful if we could TELL the node which path to use. I understand that is
being worked on.  Thanks!

the easiest way is to use the

the easiest way is to use the command:

traceroute DISTANTNODE

It will show you every hop that the traffic takes to get to that node.

Example:
╰─➤  traceroute WA5EOC-UBM2-CH
traceroute to wa5eoc-ubm2-ch.local.mesh (10.44.181.237), 64 hops max, 52 byte packets
 1  localnode (10.43.81.81)  0.652 ms  0.466 ms  0.467 ms
 2  mid2.w2mvr-unsm2-101 (172.31.203.230)  56.667 ms  55.873 ms  56.794 ms
 3  wa5eoc-ubm2-mont (10.118.212.43)  182.320 ms  70.375 ms  112.319 ms
 4  wa5eoc-ubm2-eoc (10.118.210.248)  83.657 ms  110.267 ms  154.462 ms
 5  wa5eoc-ubm2-ch (10.44.181.237)  401.289 ms  120.826 ms  187.664 ms

which path?
Thanks!  This works great!  (After I figured out the command is spelled tracert on my windows 7 PC).

MTR
MTR (mytraceroute) is a very handy utility for tests like this.  It's available for both Linux and Windows.
